How yo add an array

Question

If I have an array of predetermined numbers

I.e.

Var prices = [10, 20, 30, 40];

And the user inputs me a value

I.e.

Var increase = parseInt ( input());

How can I program JavaScript to add the user increase to my original array and output the new array?

I.e.

Input = 2

Output
[12, 22, 32, 42]
